Abstract:

I will talk about Theseus, an efficient algorithm for the design of quantum experiments, which we use to solve several open questions in experimental quantum optics. The algorithm' core is a physics-inspired, graph-theoretical representation of quantum states, which makes it significantly faster than previous comparable approaches. The gain in speed allows for topological optimization, leading to a reduction of the experiment to its conceptual core. We demonstrate Theseus on the challenging tasks of generating and transforming high-dimensional, multi-photonic quantum states. In each case, we can interpret, generalize and conceptually understand the solutions without performing any further calculations. We argue that therefore, our algorithm contributes directly to the central aims of science.
